Proteomic data exchange and storage: using proteios

Proteios (http://www.proteios.org) is an initiative for the development of a comprehensive open source system for storage, organization, analysis, and annotation of proteomics experiments. The Proteios platform is based on existing principles for proteomics data publishing and data exchange.

Towards a strategic mindset for logisticians - the challenge of complexity

Purpose The aim of this paper is to provide insights into, and perspectives on, the transformation of mindsets for logisticians. We argue that by exploring paradoxes inherent in the efficiency-focused paradigm of today, a strategic mindset can emerge in which central logistics management issues can be addressed, understood, and dealt with in order to enhance supply chain effectiveness and innovati

Propagation prediction at 2.5 GHz close to a roof mounted antenna in an urban environment

This study investigates the accuracy with which a simple propagation model based on geometrical optics (GO) and uniform theory of diffraction (UTD) can be used to predict the fading characteristics near a base station. The model uses both standard first order three dimensional GO and UTD to simulate near field propagation at the base station. Simulation results are compared with data from a measur

Sum rules and physical bounds in electromagnetic theory

Sum rules are useful in many branches of physics and engineering as they relate all spectrum parameter values with their asymptotic expansions. Properties of the dynamic response can hence be inferred by the, in many cases much simpler, static response. This has e.g., been used for lossless matching networks, radar absorbers, extinction cross section, partial realized gain of antennas, high-impeda
